Forms Data Controls :: Dollar Value Displayed As Decimal From Database
Dec 6, 2010
I'm using a ListView control and have everything working the way I want, except the display of the data. I have an asp:Label control for each field, and if I have "Text='<%# Eval("MinimumValue") %>' " everything works fine, except the dollar values from the database are displayed as decimal values (how they are stored in the database). I tried adding .ToString("C") to the end of the Eval and I keep getting the same error. I've included the block of tests (with error) from my immediate window. Is the problem just that I'm on the aspx page and need to do formatting in the code behind?

Using ASP .Net 4.0,Entity Framework and EntityDataSource.
I have some currency fields that are defined as Decimal. I would like to allow the user to enter a (leading) dollar sign in these (TextBox form fields). Although, when the EntityDataSource goes to save the changes to the datbase, it throws:
Error while setting property 'QuotedMaterial': 'Cannot convert the value of parameter 'QuotedMaterial' to the type 'System.Decimal'.'.
Does anyone know how I can "tell" the EF to allow dollar signs and convert (drop) them accordingly? I am trying to avoid creating my own Data or Business Logic layer for this particular application. I would like to stick with the EntityDataSource and other
"built in" controls to minimize the C# code behind as much as possible.
I guess my only alternative is to deny $ (Dollar Signs) (and commas too for that mater, it doesn't like them either). The problem is I am porting a legacy application and I would like to keep it as close to the original as possible (and they are currently
allowed to enter dollar signs in this application). You see, they use copy/paste for data entry quote often on this particular form and it just so happens that the source data (they are copy/pasting from) always has a $ in it...

I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.
I used:
xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";
And no works (h is for rows, N is the column. Into a foreach).

i would like to find out how to go about displaying data from multiple database tables on the same page. What i mean is it would look like the feeds on the facebook home page where you can see the information like newply uploaded photo or a new post.
I have two tables, and i want to display any newly created row on my home page from either table in the same control. Currently, i have two gridviews, but i want the data from both tables be displayed together.

It's trying to update a column which data type is set to decimal. Just so you know what I really need out of it, here is an example:
[Code]....
The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?

In a formview I need to present a new value calucalted by dividing one field value by another. I need to present the result to one decimal place. The code I am using is the following, however it presents the resulting value rounded up or down to the nearest whole value:
<asp:label id=lblTotal text='<%# Convert.ToInt32(Eval("Value1")) / Convert.ToInt32(Eval("value2")) %>' runat="server"></asp:label>
I did try and insert refernces to {0:N1} but this just threw asp.net errors. Any advise on how I can guarantee that the value calculated is presented to one decimal place?

I want to update a record in a detailsview which contains a decimal value which I would like the field to formatted as currency while editing.
When I try to update the record I get an error about trying to pass a formatted value to an unformatted table column. The ApplyFormatInEditMode is set to true and you are cautioned by intellisense about unformatting befor updating the record. This is databound field.
Is this a simple as x = Val(detailsviewrow(1).tostring) ?

I've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?

I have a master gridview that I am populating data to. I am am also counting records of open and closed and I want to display the percentage closed. I am using the following code. It always rounds up. In other words, if the actual calculation shows it to be 0.16 it will always display in the label as 0.2 I cannot figure out what I am doing wrong. If I just take two numbers and divide them in the code it displays 0.16676767. Here is the code I am using. The first line is on up in the code but I plugged it here to show you that I am using a session variable to add to as I rip through the code. I have all three of the variables I am placing the session variables in defined as Dim xxxxx as single.

when updating a decimal field in a GridView all is fine when using e.g. "2.3" ("." to separate the fraction!)
However, when using "2,3" I get e formatstring exception!
I tried "regularExpressionValidator/RequiredFieldvalidator" but did not succeed! Tried also with FormatString like {0:n}.....
Questions:
is this controllable by "Culture / UICulture" in web.config (played with it without success!
How do I best check for correct input i.e. force "." as separator
Can I use the "DataFormatString" property for the appropriate GridView field (like {0:n}) ......

Some values are returning 2.0 but I need it to be 2.00 as this is a money value that is displayed to the web page.
I am doing:
Math.Round(value, 2);
Is there a way to force it to 2 numbers after the decimal?

I have my SQL query posted in the "SQL Server etc..." forum, and I'm posting the code here in case there's something wrong with how I display the data in the GridView. The GridView should display 2 rows, but displays only 1.
